Teast.SimpleCQRS
This is a simple "CQRS"/EventStore implementation that can be used to simplify the boiling plates when building such solutions.
Implementation
The idea is to have Command
objects that drives changes to your entity.
One implementation is to create an CommandHandler
class that can handle your Commands
and that uses your Aggregate
to generate an corresponding Event
object.
Difference between Command and Event
The main different between this two objects is that a Command
should be validated and can be rejected while an Event
should never be validated and instead always be applied.
A Command
that is accepted should generate an Event
and the Event
is the one that should be stored in your data storage and then later on read from data storage when you re-play your entity through an Aggregate
Difference between snapshot and projection
a projection should always represent latest state of your entity while a snapshot can be from any state of your entity.
IStorage
This interface is the glue between Simple.CQRS and your data storage.
When Repository
needs to fetch events, snapshot, versions, etc from the data storage it will use an object that implements this interface.
Repository
This abstract class will take care of extracting changes from an existing Aggregate
for saving to data storage or to create an Aggregate
based of data fetched from IStorage
.
Aggregate
Aggregate handles creation of events and to load events.
Event
Represents an change to your entity. All changes that you support should inherit from Event
Data
This class represents an snapshot (or projection) of your entity. It is possible to use SimpleCQRS without having an dedicated snapshot class.
